Recent vehicles are increasingly equipped with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution emitted by our vehicles. This is exactly the subject matter of our article content of the day, we are going to look at the problems of the lambda sensor on Chevrolet Silverado , this sensor as well known as oxygen sensor plays an important role. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor problems on Chevrolet Silverado and how to solve them.


What is a lambda fonction on Chevrolet Silverado?

So we begin our content page with the benefit of a lambda sensor on Chevrolet Silverado , we will first see what is the purpose of this probe and then how it works.

Role of a lambda sensor on Chevrolet Silverado

First created by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Chevrolet Silverado , its objective is to regulate the amount of oxygen in the exhaust gases, this will allow the engine to adapt the air/fuel mixture to reduce the pollution emitted by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor operation on Chevrolet Silverado

Before describing you the different problems of lambda probe on Chevrolet Silverado , we will look a little more in detail at its working to allow you to understand exactly how it works and thus to consider more serenely the correction of a problem related to it.
As we informed you, a lambda probe has the task of managing the amount of oxygen present in the exhaust gases . One could naively presume that this data is calculated upstream of the combustion but it is on the contrary measured at the engine outlet . With the EURO 1 standard there was only one lambda sensor needed before the catalyst, but with the arrival of more drastic standards there are now 2 lambda sensors, one before and one after the catalyst . The benefit is to have more precise data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline inserted into the engine to improve the combustion .

Lambda sensor issue on Chevrolet Silverado

Finally, we are now going to attack the part you are absolutely most keen on this content page, what to do if you have a lambda sensor issue on Chevrolet Silverado . In a first step we will see how to identify a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Chevrolet Silverado is HS

It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this statistics can fluctuate according to the year of your Chevrolet Silverado, your driving, and the good functioning of your engine. A poorly maintained engine that releases unburned gases may permanently corrupt your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Chevrolet Silverado may be the engine light turns on, if you want to turn off the engine light of your Chevrolet Silverado, do not think twice to seek advice from our dedicated content page to see the procedure to follow. The only effective technique to make sure that you have a lambda sensor issue on your Chevrolet Silverado and to complete your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Chevrolet Silveradohow to read the fault code of a Chevrolet Silverado. Please be aware that if you have problems with one of your lambda sensors, the only remedy to solve them will be to replace the faulty sensor.

How to replace a lambda sensor on Chevrolet Silverado?

And at last, we are going to focus on the correction of lambda sensor problems on Chevrolet Silverado , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to execute and you will have the ability to do it yourself with a minimal of tools and mechanical know-how. A lambda sensor is worth between 25 and 50€ , it is better to replace the 2 lambda sensors present upstream and downstream of your catalytic converter because if one of them is faulty the second one risks to drop you quickly. To replace it, it will be necessary to put your Chevrolet Silverado on candles and at the level of your catalyst unscrew your probes, disconnect them, reconnect them and screw the new ones . Once re-connected, you should not have any more problems with your lambda sensor on Chevrolet Silverado.
